WebScheduling is the process of optimizing limited resources, depending on the objectives. Scheduling problems are one of the decision-making problems that play a critical role in production and service systems. Continuing production regularly and WebFor the first category of problem which is designated as the permutation flow shop scheduling problem with sequence-dependent setup time (PFSP-SDST), a large number of works have been carried out. This setup time depends on each job to be processed; for example, a big job requires more time of preparation than a small one.
